| 摘要 |
A Voice over Internet Protocol (VoIP) terminal and an information management method thereof, in which when any terminal requests receiving terminal information from any receiving terminal in order to communicate with the receiving terminal, a request message for receiving terminal information is transmitted to at least one terminal of a multicast group to which the receiving terminal belongs, and communication is conducted based upon the receiving terminal information received from the terminal of the multicast group. As a result thereof, when the telephone number of the receiving terminal is not known to a user or stored, the user can obtain the telephone number of the receiving terminal without having to inquire of a server or call center that has stored the telephone number of the receiving terminal.
